Suntech Protocol - Module Battery Information.
Looking at the protocol code, shouldn't the battery value be interpreted directly in the "case "STT" on line 406, instead of in the " if (getHbm(deviceSession.getDeviceId()) == 1)" ?
I made the following change and now the module battery value is displayed.
switch (type) {
case "STT" -> {
position.set(Position.KEY_STATUS, Integer.parseInt(values[index++]));
position.set(Position.KEY_INDEX, Integer.parseInt(values[index++]));
// Skip the next intermediate value
index++;
// KEY_BATTERY
if (index < values.length) {
position.set(Position.KEY_BATTERY, Double.parseDouble(values[index++]));
}
}
case "EMG" -> position.addAlarm(decodeEmergency(Integer.parseInt(values[index++])));
case "EVT" -> position.set(Position.KEY_EVENT, Integer.parseInt(values[index++]));
case "ALT" -> position.addAlarm(decodeAlert(Integer.parseInt(values[index++])));
case "UEX" -> index = decodeSerialData(position, values, index);
}
I believe other types also support it and it should be only included with HBM = 1, so the original code looks correct and what you have is incorrect. But maybe you have some other protocol documentation that you didn't share.
Anton, there are 7 decoding methods in SuntechProtocolDecoder.java, which determines that the information received from a specific module is decoded by method A or B...? In my case, I have modules ST340, ST340UR, ST340RB, ST310UC2.
Based on the documentation and table provided by suntech, I implemented it like this, the internal battery they call batteryBackup.
if (protocol.startsWith("ST3") || protocol.equals("ST500") || protocol.equals("ST600")) {
index += 1; // model
// implementado por Junior Melo 11/06/2024
String batteryBackup; // battery internal in volt
if (type.equals("ALT") || type.equals("EMG") && values.length == 20) {
batteryBackup = values[18];
double voltage = Double.parseDouble(batteryBackup);
double batteryPercentage = 0;
if (voltage >= 4.06) {
batteryPercentage = 100;
} else if (voltage >= 3.97) {
batteryPercentage = 90;
} else if (voltage >= 3.89) {
batteryPercentage = 80;
} else if (voltage >= 3.83) {
batteryPercentage = 70;
} else if (voltage >= 3.77) {
batteryPercentage = 60;
} else if (voltage >= 3.75) {
batteryPercentage = 50;
} else if (voltage >= 3.73) {
batteryPercentage = 40;
} else if (voltage >= 3.66) {
batteryPercentage = 30;
} else if (voltage >= 3.53) {
batteryPercentage = 20;
} else if (voltage >= 3.49) {
batteryPercentage = 10;
} else {
batteryPercentage = 0;
}
position.set(Position.KEY_BATTERY_LEVEL, batteryPercentage);
}
if (type.equals("STT") && values.length == 21) {
batteryBackup = values[19];
double voltage = Double.parseDouble(batteryBackup);
double batteryPercentage = 0;
if (voltage >= 4.06) {
batteryPercentage = 100;
} else if (voltage >= 3.97) {
batteryPercentage = 90;
} else if (voltage >= 3.89) {
batteryPercentage = 80;
} else if (voltage >= 3.83) {
batteryPercentage = 70;
} else if (voltage >= 3.77) {
batteryPercentage = 60;
} else if (voltage >= 3.75) {
batteryPercentage = 50;
} else if (voltage >= 3.73) {
batteryPercentage = 40;
} else if (voltage >= 3.66) {
batteryPercentage = 30;
} else if (voltage >= 3.53) {
batteryPercentage = 20;
} else if (voltage >= 3.49) {
batteryPercentage = 10;
} else {
batteryPercentage = 0;
}
position.set(Position.KEY_BATTERY_LEVEL, batteryPercentage);
}
}
@AntonioJunior, I think this approach is perfect. I will try it. Thanks for sharing.
Hello everyone, does anyone know if the Suntech protocol decoder can decode the module battery value? Below is what the module reports to the platform.
The module battery value is 4.1, that is, the penultimate value.
When trying to retrieve the value of the "battery" attribute using computed attributes, I receive the following error:
However, using "power" I receive the vehicle's battery value correctly.
